Add idle service to clean orphan downloads.

Periodically reconcile database against disk contents.  This handles
the case where a user/app deletes files directly from disk without
updating the database, and the rare case where a database delete
didn't make it to deleting the underlying file.

Also cleans up any downloads belonging to a UID when removed.
